It will also be seen that the vertical bars of the framemay be provided with an offset inwardly as at C in which the sideperipheral edges of the screen will seat as means to prevent inwarddeflection of said screen.

Positioned inwardly of the screen and being carried by the vertical sidebars of the frame 55 are a plurality of horizontally positioned slats I2spaced apart vertically, the ends of the slats, each having a ball l3formed thereon to rockably and slidably engage in grooves 14 that arepositioned in the confronting sides of the vertical bars substantiallytheir entire length, said grooves having a diameter equal to that of theball to retain the same therein for permitting sliding and rockingmovement of the neck [5 as carrying means for its respective ball.

To rock the slats is through the medium of a chain [6, said chain beingcarried and engaging over a flanged roller I! that is rotatable on ahorizontal shaft [8 which has its ends rigidly secured in the verticalbars of the rectangular frame at their upper extremities. The chaindepends downwardly from the roller, the lower ends of said chain beingsecured to oppositely disposed edges of a lowermost slat I!) which issimilar as slats l2 but being increased in thickness to avoiddeflectionwhen the slats are raised upwardly as later described. It will be seen.that the slats have their respective side edges secured to the chain inequal spaced relation ther'ealong, whereby when the chain is gripped byan operator, the slats may be rocked to a desired slant, and also theslats may be rocked by gripping a slat to rotate the same on itslongitudinal axis, which in turn will rock the other slats,correspondingly. The side edge of each slat is secured to its associatedlink of the chain by a pair of cars 20 intcgrally joined to said slat,and between which the link will engage, and through which a pin 2iextends :as securing means for the chain to said slats.

The slats may be raised upwardly in stacked relation, if so desired, bypulling downwardly the free end portion of a pair of cables 22, saidcables engaging over their respective flanged rollers 23 that arejournalled on shaft IS, the fixed portion of the cables running throughthe slats and being fixed at their lower extremities to the lower slatl9 by any suitable means such as by an eye D as shown in Fig. 4. Bypulling the free end of the cables downwardly, the lower slat will moveupwardly to contact its adjacent slat, which in turn engages its nextsucceeding slat, and so on, until all slats are contactingly engaged andpositioned rearwardly of the plate 8 as obscuring means for the slatsfrom an external view. To retain the slats, upwardly positioned, is byforcing the free end of the cables into their respective hooks 24 thatare secured adjacent the lower end of the vertical bars, said hookshaving their members diverging outwardly to permit wedging of the cableswhen forced inwardly therebetween. It will be understood, however, suchmethod of fastening the free end of the cables may be varied aspreferred by the manufacturer.

As a means to partially obscure the rollers and 50 the shaft from viewinternally of a room, there is provided a member, angle-like in crosssection, one leg, as at 25, depending downwardly to enclose the rollers,while leg, as at 26, of the angle is secured to the inner side of theupper bar of the rectangular frame by screws 21 as shown in Fig. 4.

To look the slats, against opening from a closed position and aspositioned in overlapping relationship, is through themedium of one ormore leaves 28, which are hingedly connected to the inner peripheraledge of the vertical bars, said leaves being adapted to rock inwardly toengage on the slats and retain the same closed against force that may beapplied externally on said unit.

While the invention illustrates the free manipulating ends of the cablesexternally applied of the window, the same may be run through thebuilding, if so desired, without departing from the spirit of thisinvention, and furthermore while the invention otherwise is shown anddescribed specifically, the details such as to the exact type ofmaterial, proportion, and arrangement of components thereof may bevaried as lie within the scope of the appended claim.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:

In a combined screen and Venetian blind unit for window framescomprising a rectangular,

frame consisting of vertical bars, and horizontal bars at the upper andlower ends of said vertical bars, a screen to partially enclose theframe, a plate to enclose the remaining portion not enclosed by thescreen, said plate being secured adjacent the upper extremity of theframe, a plurality of horizontally positioned slats, means in thevertical bars to rockably and slidably carry the ends of said slats,means for rocking the slats about their longitudinal axis, means toraise the slats upwardly in stacked relation to position the samerearwardly of said plate for obscuring the slats from an external view,and means to lock the slats when the same are suspended and slantinglyrocked to overlapping relationship.
